- Shellfish
- Crustaceans: Shrimp, crab, lobster, crayfish.
- Mollusks: Clams, mussels, oysters, scallops, squid, octopus.
Foods and products that may contain seafood
- Seafood-based sauces: Fish sauce, oyster sauce, worcestershire sauce (may contain anchovies).

- Processed foods: Certain soups, stews, and broths may use seafood-based stocks.
- Ethnic foods: Dishes from asian, african, and mediterranean cuisines may use seafood or seafood-based ingredients.
- Supplements: Some omega-3 supplements are derived from fish oil.
Important: Always read ingredient labels carefully, as seafood can be present in unexpected products.
Suitable alternatives
Incorporate seafood-free foods to maintain a balanced diet:
- Proteins: Chicken, turkey, beef, pork, eggs, legumes (beans, lentils), tofu, and tempeh.
- Plant-based seafood alternatives: Products made from soy, wheat, or pea protein designed to mimic the taste and texture of seafood.

Important: Consult with a registered dietitian to ensure nutritional needs are met while avoiding seafood.
Practical tips
- Read labels diligently: Ingredients can change, so always check for seafood derivatives.

- Educate yourself and others: Understand the various names and forms of seafood to avoid accidental exposure.
- Carry emergency medication: If prescribed, always have antihistamines or an epinephrine auto-injector on hand.
